Droughts have emerged as a global problem in contemporary societies. China suffers from different degrees of drought almost every year, with increasing severity each year. are seasonal and can severely impact crops. This study used spatiotemporal trend characteristics analysis disaster data 1991 to 2018 Chinese provinces, addition the Mann–Kendall test wavelet analysis. The included crop damage area, drought-affected area crops, failure area. outputs crops decreased by 10%, 30%, 80%, respectively. population reduced drinking water caused drought, domestic animals were numbered tens thousands. results show that areas owing disasters, mainly distributed northern, eastern, northeaster, southwestern regions. number people concentrated northern These indicators showed general trend. Tibet, Fujian, Shandong, Jiangsu, Anhui, Henan provinces autonomous regions also slightly In particular, Inner Mongolia Autonomous Region clear significant Z-value 2.2629. this research be provide scientific evidence for predicting future trends practising best management prevention resistance.

Published: Oct. 27, 2023

The development of the Yellow River Basin (YRB) has been constrained by resource utilization, ecological conservation, and economic growth. aim this study was to establish a theoretical framework for characterizing relationships among resources, economy, ecology in YRB using panel data remote sensing from nine provinces basin 2002 2022. Furthermore, coupling coordination degree model geographical detector were used evaluate spatiotemporal relevant factors. Our findings manifold. (1) its improved varying degrees, with upstream showing stronger than midstream downstream provinces. (2) most significant growth rates observed during 2002–2006 2014–2018. However, noticeable decline occurred 2006–2010, indicating that constraints negative effects pronounced when not apparent. (3) average 2022 0.684. Excellent Shandong Province Henan Province, good Shaanxi Shanxi Province. (4) In initial part period, water supply, demand, allocation had strong on degree. Over time, focus shifted single system multiple systems, which increased similarity explanatory power different Additionally, an in-depth analysis factors conducted characterize policy orientations periods YRB. Policy recommendations provided basis natural conditions socio-economic have implications high-quality Generally, our results provide key insights will aid coordinated sustainable regional development.

The sustainability of desalination as a remedy to the water crisis in the agriculture sector: An analysis from the climate-water-energy-food nexus perspective

Agricultural Water Management, Journal Year: 2023, Volume and Issue: 286, P. 108407 - 108407

Published: June 10, 2023

Over the years, desalination has become integral to water resources management, primarily in coastal semi-arid arid regions. While desalinated seawater mainly been supplied municipal and high-revenue industries, agriculture sector faces increasing irrigation demands, making it a potential user. This review assesses sustainability of using for irrigation, shedding light on its limitations potential. Using presents challenges, including high energy consumption, contribution climate change, agronomy-related concerns. However, evidence suggests that these challenges can be addressed effectively through tailor-fitted strategies. That said, conventional binary decision-making paradigms label practices as good or bad focus singular, isolated aspect are insufficient evaluating due complex interconnected nature issues involved. To overcome this, climate-water-energy-food (CWEF) nexus concept is proposed comprehensive framework assessment. Adopting CWEF approach allows better understanding associated with encompassing social, economic environmental ensure effective management crucial tailor projects specific regional conditions employ either prophylactic corrective By embracing approach, informed decisions made regarding future utilization contributing broader goals.

Understanding advances and challenges of urban water security and sustainability in China based on water footprint dynamics

Ecological Indicators, Journal Year: 2023, Volume and Issue: 150, P. 110233 - 110233

Published: April 10, 2023

Sustainability of China's numerous cities are threatened by both quantity- and quality-induced water scarcity, which can be measured the footprint from a consumption (WFcons) or production (WFprod) perspective. Although WFcons was widely assessed, changes in WFprod were still unclear. A large-scale decrease urban China found, with average decreasing 13.8 billion m3 to 10.3 per capita 1614.8 m3/person 1184.0 (i.e., falling more than quarter just six years). Such shrinkage particularly evident drylands, eliminating deficit Xi'an Xining. The reduction grey caused implementing pollution prevention policies other relevant measures played most important role savings. In future, implementation updated discharge standards is projected allow escape deficits; however, rapid growth domestic ecological blue urbanization greening would destabilize this prospect. Thus, attention should given restriction further alleviate scarcity China.

Modeling the water-energy-food-environment nexus and transboundary cooperation opportunity in the Brahmaputra River Basin

Journal of Hydrology Regional Studies, Journal Year: 2023, Volume and Issue: 49, P. 101497 - 101497

Published: Aug. 2, 2023

The Brahmaputra River Basin. Basin (BRB) is the most environmentally fragile and politically unstable transboundary river basin in South Asia. Therefore, incorporating environmental sector into water-energy-food system analysis necessary to better serve water resource management BRB. Integrated resources can provide more perspectives for alleviating political tension promoting cooperation basin. This study proposes a modeling framework explore water-energy-food-environment (WEFE) nexus analyze opportunities Employing framework, we attempt answer three questions: (1) how understand relationships between various sectors coordinate their demands? (2) How do these influence riparian countries' decisions? (3) What measures promote sustainable development of BRB under climate change infrastructure development? results show that trade-off curve economic benefits costs has declining marginal value When constraints are raised, countries inclined cooperate obtain benefits. Full increases prompts take greener road among shared socioeconomic pathways (SSP126). Water project construction improve utility country, thus enhancing its discourse power on benefit reallocation.

With the global issues of extreme climate and urbanization, ecological security patterns (ESPs) in Qinling Mountains are facing prominent challenges. As a crucial barrier China, understanding characteristics ESPs is vital for achieving sustainable development. This study focuses on Yangxian employs methods such as machine learning (ML), remote sensing (RS), geographic information systems (GISs), analytic hierarchy process principal component analysis (AHP–PCA), minimum cumulative resistance (MCR) model to construct an network based multi-factor sensitivity (ES) conduct quantitative spatial analysis. The results demonstrate that AHP–PCA method ML overcomes limitations single-weighting method. were established, consisting 21 main secondary sources with area 592.81 km2 (18.55%), 41 corridors length 738.85 km, 33 nodes. A coupling relationship among three dimensions was observed: comprehensive sensitivity, ESPs, administrative districts (ADs). Huangjinxia Town (1.43 C5) Huayang (7.28 C4) likely have significant areas vulnerability, while Machang Maoping important ESPs. ADs focus protection management. second corridor indicated high-quality construction, necessitating implementation strict policies area. innovation lies utilization methods, RS technologies, pattern planning propose new perspective space. provides foundation urban rural will help facilitate development region.
